1. Motorized strength training machine comprising an electric motor unit, an axle and a first user force input element, said electric motor unit comprising an electric motor, said electric motor being connected to said axle such that rotation of the electric motor drives said axle and rotation of the axle drives the electric motor, and said first user force input element being connected to said axle such that rotation of said axle displaces the first user force input element and displacement of said first user force input element rotates the axle, said machine further comprising a mechanical range limiting mechanism comprising displaceable first and second rotation limiting stop elements which can be mechanically locked at different angular locations around the axle to mechanically limit the range of rotational motion of the axle, characterized in that the mechanical range limiting mechanism comprises a motorized displacement mechanism which is arranged to displace the first and/or second rotation limiting end stops angularly around the axle based on inputs from a controller.
